The RACROUTE REQUEST=LIST macro, used to build in-storage copies of general resource profiles, has two exits: the preprocessing/postprocessing exit and the selection exit. RACF® calls the preprocessing/postprocessing exit before RACROUTE REQUEST=LIST processing to allow the installation to alter REQUEST=LIST processing options and after REQUEST=LIST processing to perform housekeeping. RACF calls the REQUEST=LIST selection exit to resolve conflicts between new and existing profile information.
